Which SDK this is regarding: com.auth0.android:auth0:1.12.0  
Running on Android phones, v12

I am having trouble while redirect back to my app using my specified Auth0 callback URL, it goes to a page that says “Not found” in plain text with no other information.

My specified callback URL is https://{my-tenant}.eu.auth0.com/android/{my-android-package}/callback.

In Android V11 and lower versions, able redirect back to application

Hey there!

Can I ask you to raise it as a GitHub issue in the Auth0 Android repo so we can work on that directly with the repo maintainers? Once you have a link to it you can share it here so we can ping them. Thank you!
